Hall simulates the sound of large enclosed spaces. Hall offers flexible control of a 3-band crossover reverb network. There are independent decay controls for the low and high band, as well as independent level controls for low, mid, and high band. This is the go-to algorithm for beautiful realistic spaces or for reverb sounds just beyond the boundary of realism.

Hall Algorithm Controls
Mix [MIX]
wet/dry mixer, 100% is all wet signal
Decay [DECAY]
master decay in seconds or note-based in Tempo Mode
Size [SIZE]
hall size
PreDelay [PREDLY]
pre-delay in milliseconds or note-based in Tempo Mode
Low Band Reverb Level [LO-LVL]
boost/cut of LOW reverb with cut-off at 300 Hz, -100 effectively cuts all of the low band reverb
High Band Reverb Level [HI-LVL]
boost/cut of HIGH reverb with cut-off at 1500 Hz, -100 effectively cuts all of the high band reverb
Low Band Decay [LO-DCY]
decay of LOW reverb, scales the [DECAY] time
Hi Band Decay [HI-DCY]
decay of HIGH reverb, scales the [DECAY] time
Modulation Level [MODLVL]
increases random modulation of reverb tails
Mid Band Reverb Level [MIDLVL]
boost/cut of MID reverb (between 300 and 1500 Hz), -100 effectively cuts all of the mid band reverb
Output Level
At 0 the output level is unaffected. Increase the output level of the effect by up to 20 dB or lower by 30 dB.
Tempo is turned ON/OFF on the H9 by simultaneously pressing the Right Footswitch and the PRESETS button. With Tempo OFF, tapping can be used to adjust delay parameter values (displayed as milliseconds or Hz). With Tempo ON, tempo is in BPM.
Turn effect on or off..
The Middle Footswitch can be programmed to act on the loaded Preset as a programmable controller allowing the user to switch between the normal Preset parameter values and a programmed, alternate set of parameter values. It’s like having two Presets in one.
If Tempo is ON, the display indicates the current tempo in BPM (30 to 500 BPM) while tapping and the Tap LED will blink at the BPM rate. If Tempo is OFF, the display indicates the parameter value (milliseconds for most algorithms).
